IM PROVEM ENT IN PLOW-CLEVISES.

Spcciication forming part of Letters Patent No. 208,899, dated October 15, 1878; application led February 11, 1878.

lo all whom 'it may concern Be it known that I, HENDERSON EsTEs, of Boltons Depot, Hinds county, in the State of Mississippi, have invented certain new and useful Improvements in Plow Clevises, of which the following is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specilication My improvement consists in making the clevis in two parts, which are separable from each other, the front bar having an overlapping joint, which ts over the other. The clevis is pivoted to the main bolt, on which it turns.

In the drawings, Figure l is a perspective view, showing the clevis open for the reception of a ring or link. Fig. 2 is a side View, showing the clevis closed in position for use.

A is the end of the beam of the plow or other implement. The clevis is attached to the beam by a bolt or rivet, Bpassing through both parts of the clevis and through the beam, and is secured in position upon the beam by a removable pin, C, also passing vertically through both parts of the clevis and through the beam. The clevis consists of two parts, D and D', similar to each other in every respect, except that one ot' them, D', is provided with a screw-threaded hole to receive the screw-threaded end of the bolt B when a screw-bolt is used.

A description of one of the parts D or D' applies equally to the other as far as any novelty is concerned. l is the hole for the rivet or screw B, and d' is a hole through which the key-pin O passes.

E is the vertical portion of the clevis, made fiat upon one side, at e, to t the flat portion of the other part. It has the usual recesses to hold the draft-link or the loop-strap of the single or double tree at any height.

e2 is a projection or lip, which stands out at right angles to the tlat part e, and which lits the end e3 of the other part. e* is a hook which engages the projection e2. Thus the draft-strain is brought directly upon the horizontal bars of the clevis both at top and bottom.

Vhen removing a link, Ste., from the clevis it is only necessary to take out the pin C and turn the parts D D' to one side, and, the link being moved above or below the lap-joint, the parts are separated, as shown in Fig. l, and the link removed. a rivet, B, would answer as well as a screwbolt, because it is not necessary to remove the clevis for any purpose, and it becomes a xed attachment to the plow, that can be neither lost nor stolen.

I claim as my inventionl. The two-part clevis D D', separable from each other at the lap-joint at E, and pivoted to the beam by the'main bolt B, substantially as set forth.

2. The combination, ina clevis, of the two parts D D', with lap-joint at E'and catches c2 c", for the purpose set forth.
